Hi John,

iNSpect is a little picky on the trace files. That's at least what I
found....

Let me explain how I started my iNSpect experience (using wireless1.tcl
from the examples in ns)

1) make sure the you have
$ns_ node-config -macTrace ON
in your wireless1.tcl file. iNSpect needs the MAC trace.

2) run ns wireless1.tcl

3) FIX your trace file!
iNSpect requires the initial node position to be in the first few lines
of the trace file. Use a python program called traceFix.py
(http://toilers.mines.edu/Public/NsInspect) to do this.

4) create a matching .config file for iNSpect. The most important thing
seems to be to have the number of nodes right (and the size of your terrain)

5) run "iNSpect -t wireless1.config wirelss1-outFix.tr"

Another method is to create a viztrace file, using a perl script called
portInspect (http://www.geocities.com/vin_sdm/ns2-wireless.htm)

This requires you to have a motion file for iNSpect.
If you have your own motion file you normally wouldn't use random
motion. In this case make sure that you use calcdest to create the GOD
information. Be aware that calcdest and iNSpect require the motion file
to be in different order: calcdest requires anti-chronological order,
iNSpect requires chronological order.

I hope this create more insight than confusion...
